This patch set adds support for interrupts coalescing in dpaa2-eth. The first patches add support for the hardware level configuration of the IRQ coalescing in the dpio driver, while the ones that touch the dpaa2-eth driver are responsible for the ethtool user interraction. With the adaptive IRQ coalescing in place and enabled we have observed the following changes in interrupt rates on one A72 core @2.2GHz (LX2160A) while running a Rx TCP flow. The TCP stream is sent on a 10Gbit link and the only cpu that does Rx is fully utilized. IRQ rate (irqs / sec) before: 4.59 Gbits/sec 24k after: 5.67 Gbits/sec 1.3k Changes in v2: - documented the new qman_clk field Ioana Ciornei (5): soc: fsl: dpio: extract the QBMAN clock frequency from the attributes soc: fsl: dpio: add support for irq coalescing per software portal net: dpaa2: add support for manual setup of IRQ coalesing soc: fsl: dpio: add Net DIM integration net: dpaa2: add adaptive interrupt coalescing .../net/ethernet/freescale/dpaa2/dpaa2-eth.c | 11 +- .../net/ethernet/freescale/dpaa2/dpaa2-eth.h | 2 + .../ethernet/freescale/dpaa2/dpaa2-ethtool.c | 58 +++++++++ drivers/soc/fsl/Kconfig | 1 + drivers/soc/fsl/dpio/dpio-cmd.h | 3 + drivers/soc/fsl/dpio/dpio-driver.c | 1 + drivers/soc/fsl/dpio/dpio-service.c | 117 ++++++++++++++++++ drivers/soc/fsl/dpio/dpio.c | 1 + drivers/soc/fsl/dpio/dpio.h | 2 + drivers/soc/fsl/dpio/qbman-portal.c | 59 +++++++++ drivers/soc/fsl/dpio/qbman-portal.h | 13 ++ include/soc/fsl/dpaa2-io.h | 9 ++ 12 files changed, 276 insertions(+), 1 deletion(-)
